cant set cut off mask anymore #4991
Description
Description
When a root prim has an alpha texture and any child prim has non-alpha texture (specifically on face 0), then the Alpha mode drop-down is unavailable. In older viewers, this Alpha mode drop-down would be available.
- Rez 2 default box prims
- Box A, leave as default plywood
- Box B, set the diffuse Blinn-phong texture to "Hair Straight Thick" from the Library
- Box B, Set Alpha mode to alpha mask with a mask cutoff of 5
- Link Box A & Box B with Box A as root.
- Edit the linkset and observe that you can change the alpha mode between None, blend and mask as expected
- Unlink the boxes and relink with Box B as root
- Edit the linkset and observe you cannot change the alpha mode.
Bug does not reproduce on the LL pre-PBR viewer https://releasenotes.secondlife.com/viewer/6.6.16.6566955269.html
Well...
Note: Depending on how the object is selected in 6.6.16.6566955269 it will work or not. If edit mode is enabled (ctrl+3) and the alpha object is clicked, then the Alpha mode drop-down is available. If the non-alpha object is clicked then the Alpha mode drop-down is not available

Workaround: Click Edit linked in the edit tool floater, deselect the plywood (non-alpha) prim, edit the alpha mode as normal.
